T 0 all whom it may concern Be it known that we, GrnoRGn HERBERT BENTLEY and EDMUND GARDNER 'Ar'rLnBY, both subjectsof the King of Great Britain, residing at London,`lngl`and, haveinvented new and useful Improvements in'Gas Producers, ofwhich the 'following' is aspeciiication.

This invention relates tojgas producers, reto-rte andthe like, used in the production of gas, and the objects ofthe invention are (1) The provision of means forevenly agitating the upperuportion oftherash bed and lower portion of the incandescent fuel bed.

2) or air 2nd bed.

(8) The reduction ofthe cost ofagas producer or retort by the reductionin size of the ash pan, and in the case of a producer by the eliminationl of the revolving l,grate usually employed.

v'lhe gas producer comprises a shell preferably circularin cross section'to which 4fuel isv supplied at the-top and is maintained in a state of incandescence byl a blast of air vor air and steam. The shellmay be carried by columns and-has beneath it a rotating ash pan supported on rollers Aor balls.

According to tlhis invention a blast tube passes centrally through, is secured'to and rotates with' the ash pan. The tube? has mounted upon its upper end armsv at such a heightthat the upper surfaces 0f the arms extend to the top of the ash bed, that is, to slightly below the Vhollow shell. The arms are preferably triangular pyramids or plough-shaped land are hollow andy are provided with outlets. rlothe end of the arms is preferably secured ayhollow ring which preferably entends beneathV and is protected from excessive wear and heating by the wall of the casing. The ringis provided with perforations in its bottom or'rear walls or in both.V An air supply is connected to the blast tube, 'the air passing;'through the tube to the arms and the ring and issuing from the perforations in them escapes to the fuel in the casing at points in the upper level of the ash bed whereby the air does not pass through the bulk of the ash bed 'asis usual 'and is moreover supplied to that vpart of The distribution ofthe blast of air steam evenly in thetop of the ash the fuel which lhas just been agitated .bythe arms. n

The arms may bel providednwith upwardly extending lugs forfagitatngl the fuelpr'eferably so situated relatively to the perforations in the rear surfaces of-the arms asto bein advance ofv them" when the'faimsr are rotated. The 'arms agitatetheffuel atthe topY of Vthe ashbed 'and 'theirm'formatifon causes the vashto be pressed downinftlhea'sh pian from which it= is renioved"by ascra'per of ordinary construction.

Steam to be added to'tlie air supply is obtained from water whichV has been heated either Vin the jaeket of the"producerorof the agitator or poker, and the-hotw'ater-'or steam is led to a sprayingV .apparatus iii-the blast tube Yp assing through 'the'ash4 pan. '-Tlhe tube arms being highlyl heated' byY the-ashes surrounding them causes'steani to be formed vwhich passes with the air blast to 4thefiiel.

In some cases' no water s'e`alfis"pr`ovided and' it istherefore unnecessary'to provide the ash pan with sidesfthe ash pan-being coninedin an air or gas-tight casing. l

The annexed drawings sh'owapparatus for usein the production ofgas mde in accordancewith thisl invention. l

Figure l is a vertical section of a gas producerhavinga water seal, Figure 2 is a` plan View of the rotary arms and ring,` Figure 3 is a verticaljse'ction of one ofthe arms, lIligure 4 is a vertical section ofv a'fgasproducer having no water seal, yl'd.`ig\`iie 5A is a'fplan view of the rotary armsfa-nd ring, Figure 6 is a horizontal section of lthe ashz'pan and Figure 7 Ais a vertical section of a modification of the producer sho-wn in Fig-ure tillustrating mea-ns for supplying water tothe blast.

In all t'lie figures lO is a shell to the top of which fuel is suppliedand llz'is an air main through which air is supplied to a blast tube l2 having at its .upper end arms 13 which extend to the top of the ash bed Yslightly below the 'shell l0. To the ends' of the arms 13 lis secured a hollow ring;v 14 which extends ybeneath and is protected by the wall of the shell 110, Steam may be supplied through a pipe lll. opening into the air supply pipe ll and provided with a valve if desired. l l

In Figures l to 3 the arms lha've holes v131y on their rear surface to allow of the eslil() cape of air and steam to the fuel. The holv low ring 14 is supplied with air and steam from the arms 13 and has holes 1111 in its inner wall and holes 142 in its bottom wall both groups of holes beingfor the exit of air and steam. On the upper surfaceof the arms 13 also are lugs 133 so situated relatively to the holes 131 as to be in advance of them when the arms are rotated. Below the shell 10 is fixed a skirt 15 which extends into an ash an 16 fixed to and rotating with the blast tu e 12 and supported by rollers 17. The ashes are pressed down into the ash pan 16 by the plough-shaped arms 13 and are removed from the ash pan by a scraper 18.

In Figures 11 to 6 the arms 13 are provided With holes 131 for the exit of lair and steam whilst the ring 14 is of oval section and is provided with holes 141 in its inner wall. In this case the end of the shell 10 is fitted with a casing 19 through which the blast tube 12 passes and to the tube is fixed a plate 20 constituting a rotating ash pan. The lashes are removed by a. pivoted scraper 21 and directed into a chute 22.

In the modification shown in Figure 7 the shell 10 has a water jacket 101 from which a pipe 102 leads to another pipe 23 and in the shell 10 are rotating pokers 24 similar to vthose disclosed in our Patent 1,391,236, of Sept. 20, 1921, which are wiater jacketed, the jacket being connected to the pipe 23 by a pipe 231. The pipe 23 leads the water or steam into the blast tube 12 and has at its end a sprayer 25 by which the heated water or steam from the water jackets is sprayed into the blast passing to the arms 13.

In Figures 1 to 3 the blast tube 12 is rotated by means of a toothed ring 121 on the ash pan 16, whilst in the other figures the ring 121 is secured to the blast tube 12. The source of power is a driven shaft 122, as indicated in the drawing.
